I have often thought about this. The most obvious is an Ars Magicka style game, where instead of the schools being inherit to the PC, place the schools in items, and allow mastery. Meaning different kinds of spells are available based on your choices.
BTW, here is a thing I like about FF7 that merits tabletop use.
Most magic comes from widgets called "Materia", but you can just consider them widgets. Each widget does one thing, sometimes in degrees. So it might boost your HP, or it might allow you to cast three fire spells.
